solubility/dilution
bayhydur 304 generally has good compatibility with the following solvents: esters, ether esters, xylene and solvent naphtha 100. however, the solubility/compatibility of the prepared solution must be tested. only use polyurethane grade solvents (water content <0.05%).


features/application                                       
due to the hydrophilic nature of bayhydur 304, it is easily emulsified in aqueous media. mainly used as a cross-linking agent for water-based hydroxyl polyols (bayhydrol®), and can also be used as a cross-linking agent for most water-based polymer dispersions with neutral ph values, including polyurethane dispersions (dispercoll® u), polyacetic acid vinyl ester, polyacrylate and synthetic rubber dispersions. after adding bayhydur 304, the prepared two-component system must be used up within the pot life. the pot life not only depends on the polymer content, but also is affected by other components such as resins, thickeners, plasticizers, etc. in many dispersions, the pot life is usually several hours, but the end of the pot life cannot be judged by the gel. in polymer dispersions with a content of 40 – 60%, it is recommended to add 3-10% of bayhydur 304 as a cross-linker with the adhesive dispersion. in order to emulsify bayhydur 304 in adhesive dispersions, effective mechanical stirring is required. manual stirring is not sufficient to ensure uniform emulsification of the system, especially in low-viscosity adhesive dispersions. insufficient dispersion can lead to particle deposition in the adhesive.
if bayhydur 304 needs to add modification additives, the additives must not contain groups that react with isocyanate, nor can they contain secondary components that can react with isocyanate. it is particularly noteworthy that any additives added must not be alkaline or contain secondary components that have a catalytic effect on isocyanate groups. even low concentrations of these components can cause viscosity to rise and even solidify.

save
this product is sensitive to moisture and should be stored in the original sealed container at a temperature not exceeding 30°c. when stored under appropriate conditions, this product has a shelf life of at least 6 months. during storage, viscosity will increase slightly.

safety: hazard identification
this product contains isocyanate, which may cause allergies in contact with skin. the safety data sheet should be read carefully. it includes information on labeling, transportation and storage, as well as information on product use, product safety and ecology.

*the above data only gives general information is not a characteristic of the product.

application
add after dexmodu® rn, the two-component adhesive must be used within the pot life. the pot life is not only related to the polymer content in the adhesive, but also to other components (such as resins, antioxidants, plasticizers, solvents, etc.) as the pot life approaches, which is usually a few hours or a working day, the adhesive becomes it is more difficult to apply and the viscosity rises quickly. eventually, an irreversible gel appears.

100 parts by mass of adhesive                                        desmodu® rn dosage
de smoco® (hydroxypolyurethane)
( polyurethane content is about 20%) 4-7

packaging
metal bottled: 0.75kg 1l bottle

storage
in stored in the original sealed packaging at 23°c, the product has a shelf life of 6 months.
all desmodu® products are sensitive to moisture conditions and react with water to produce carbon dioxide and insoluble urea, so the container must be tightly sealed. the introduction of water in any form (humid containers, aqueous solvents, humid air) should be avoided, otherwise the carbon dioxide produced may cause a dangerous increase in pressure within the container.
exposed exposure to air or light will accelerate yellowing, but will have no impact on the basic performance of the product.

disposal
useless product residues should be incinerated according to local regulations and should refer to the european waste catalog (ewc) industrial waste coding details. see material safety information for details.
no in areas subject to german packaging regulations, carefully cleaned containers or packaging may be incinerated in local or industrial incinerators. for containers that have not been cleared of contaminants, hazard labels should be retained.

viscosity (23</strongplastic technology (rim) and water-based adhesives or hot melt glue. in polyurethane resin technology, the preparation of water-based polyurethane dispersions is the most important application of vestanat®ipdi, because this starting material can be used to produce low-viscosity prepolymers and final products with low co-solvent content . it is the hard segment component of the resin. if excellent yellowing resistance and low reaction dilution are required depending on the agent or co-solvent content, you can choose polyurethane acrylates (conventional or water-based) for radiation curing based on vestanat ipdi synthesis.
vestanat®ipdi can be applied to moisture-cured prepolymers, this is another application for polyurethane resins. ipdi can make these products resistant to yellowing, low viscosity and low residual diisocyanate monomer. take vestanat®ipdi as a basic, solvent-based, high molecular weight polyurethane resin used in coatings that require abrasion resistance, especially where long-term flexibility and lightfastness are required. typical applications are artificial leather polyurethane resins or natural leather finishes. use ipdi to polyurethane alkyd resin to prepare urethane alkyd and urethane oils are primarily used to fully improve the yellowing resistance, drying properties and hardness of these resins.

application in the field of two-component polyurethane, vestanat®ipdi is an addition product with trihydric alcohol (such as: with tmp adduct) or in the form of polyisocyanate (such as: vestanat®t1890). this use is primarily for large vehicle and automotive coatings (oem and refinish).

vestanat®ipdi and its polyisocyanates can be used to prepare blocked polyisocyanates. these blocked polyisocyanates can be used for electrostatic spraying powders cross-linking agent for coatings and solvent-based industrial paints, especially can coatings and coil coatings. ipdi-based cross-linking agent gives solvent-free two-component polyurethane excellent light stability and mechanical properties. this type of system is mainly used in elastomeric coatings and casting resins. hard systems can be used as industrial materials.

activity and catalysis
aliphatic and cycloaliphatic diisocyanates are less reactive than aromatic diisocyanates. ipdi usually requires the use of appropriate catalysts to accelerate the urethanation reaction. it is recommended to use dibutyltin dilaurate as the catalyst for urethanization.
vestanat®ipdi or the adduct of this product for polyurethane formulation when used as a normal temperature cross-linking agent, dibutyltin dilaurate is often used. when complete or partial reaction of isocyanates and water (moisture) is required, a mixed catalyst of dibutyltin dilaurate and a tertiary amine such as diazodiacyclooctane (dabco) should be used. in addition to dibutyltin dilaurate, iron acetylacetonate , phenylmercury salt (coscatr83) is an effective catalyst for solvent-free polyurethanes (elastomers and casting resins). of course, at high temperatures, resin synthesis is the production of prepolymers , the reaction is also possible without a catalyst. when the temperature increases, the difference in the activity of the two isocyanates of ipdi decreases, so when the catalyst is used at room temperature, the selectivity of the prepolymer is higher. the best selectivity is achieved when the temperature does not exceed 50°c and dbtdl is added.

storage and transportation
vestanat®ipdi is packaged in non-recyclable 30kg cans and 200kg drums for supply, it is also possible to supply by tanker truck and storage tank. if moisture can be eliminated, ipdi can be stored for at least one year without affecting the quality of the above standards. long-term storage will increase the color index.

it is supplied in � and 200kg drums, and can also be supplied in tank trucks and storage tanks. if moisture can be eliminated, ipdi can be stored for at least one year without affecting the quality of the above standards. long-term storage will increase the color index.
