solubility/ dilution
generally speaking, desmodul l75 has good compatibility with the following solvents, but the storage stability of its diluted solutions must be tested. it can be dissolved in ester solvents such as ethyl acetate, butyl acetate, propylene glycol methyl ether acetate, toluene, xylene, slovesso® 100 and slovesso® a, etc. however, it cannot be dissolved in petroleum in solvent oil.
alcoholic solvents will react with deslmodu l75 and therefore cannot be used as thinners. long-term storage of low solid content resin solutions may cause turbidity and precipitation. polyurethane grade solvents (water content less than 0.05%) must be used and must not contain active ingredients.
compatibility
desmodol l75 is compatible with many polyesters, polyethers and polyacrylates, as well as various desmodul curing agents.
application
coatings formulated with desmodu l75 can be used for coating furniture, floors, metal, paper, plastics and mineral substrates.
save
desmodu l75 is sensitive to moisture. therefore, it must be stored in the original, completely sealed packaging. the recommended storage temperature is 0°c to 30°c. storage at high temperatures will cause the viscosity to increase. desmodol l75 remains stable for at least six months when stored under appropriate conditions.

application
|
in paint in the formulation, inv ptsi will react with residual moisture in the pigment and solvent to produce carbon dioxide and soluble passive compounds. theoretically, 12 grams of inv ptsi needs to react with 1 gram of water, but experience shows that it is more effective if a larger amount is used.
|
|
storage period
|
inv ptsi sensitive to moisture, therefore, must be stored in original sealed containers. if stored appropriately, inv ptsi remains stable for at least six months.

security
|
this product it is a highly reactive compound, so special care must be taken during handling.
reference should be made to the material safety data sheet, which contains information on labeling, transportation, storage and handling, product safety and ecology.
during operation, attention should be paid to current national regulations governing hazardous and corrosive substances. the reaction of this product with water, alcohol, amine, acid and alkaline solutions is spontaneous and very violent. therefore these substances should not be poured into containers containing inv® ptsi. reacts with 1 gram of water to produce 1.313 liters of carbon dioxide.
once it comes into contact with water, gas will be generated immediately, so do not close the container tightly at this time to avoid rupture. therefore, containers should be tightly packed to avoid contact with water during transportation, storage and handling.
once inv ptsi is added to the formulation, solvent system application guidelines should be followed. when using inv ptsi, if no other safety protection measures are required, its proportion of water should not exceed about 5% of the full formula.
inv ptsi it is a highly reactive compound. although its severe toxicity is very low, it can cause damage to the eyes and oral mucosa. therefore, skin, eyes and respiratory organs should not be exposed to undiluted product. therefore, when operating this product, safety goggles and protective gloves should be worn to avoid inhalation and contact with vapor and dust during spraying. it is recommended to apply lotion to protect the skin.
if the ventilation equipment in the workplace is poor, respiratory organs must be protected;
it is recommended to wear a headgear with an air inlet or outlet or a breathing device with a filter.
*100 gram solution consists of approximately 42 grams of inv ptsi reaction.

product introduction
pcdl is a polycarbonate diol ring-opened with polyol, which is professionally used in the high-end polyurethane industry.
compared with general polyester and polyether diols, pcdl shows quite excellent mechanical properties, hydrolysis resistance, weather resistance and solvent resistance. it is widely used in synthetic leather, thermoplastic polyurethane elastomer (tpu), elastic fibers, adhesives, coatings, etc. if there is a special need to improve durability, pcdl will be the best choice.
the breaking strength of polyurethane products made of pcdl is higher than that of polyurethane products made of polytetrahydrofuran ether, hexylene adipate and polycaprolactone polyol, in terms of heat resistance, weather resistance, water resistance and the solvent performance is better than other polyols, but the elongation at break is lower.
