since the date of leaving the factory, the warranty period of 44v20 is 1 year when stored according to the specified storage conditions.
safety precautions
44v20 has low toxicity in terms of respiratory inhalation and skin absorption; its low volatility makes it suitable for short-term exposure under normal conditions (such as: small leakage, sprinkled) produces very little toxicity.
however, because 44v20 is an isocyanate compound, it still has a certain degree of toxicity, which can cause moderate eye irritation and mild skin irritation, and can cause skin allergies. the maximum allowable concentration (tlv) of 44v20 in the air is 0.02ppm (0.2mg/m).
but it must be noted that when the temperature of the material is heated above 40°c (such as when melting) or in the workplace, suspended particles in the air will occur increased concentration may cause toxicity. gas masks and respirators should be worn when working in similar environments. otherwise, repeated inhalation of vapor with excessive concentrations may cause respiratory allergies.
even under normal conditions, due to the active chemical properties of 44v20, care should be taken during operation to prevent direct contact with the skin and splashing into the eyes. rinse immediately with water and wash skin with soap and water. 44v20 reacts easily with water to release carbon dioxide, so the packaging container should be kept dry and sealed to prevent water from pouring in; once water leaks into the container, be careful not to seal it too tightly and leave a vent to prevent the v from exploding. .
burning and explosion hazards
mdi series products are listed as class iii class b flammable liquids in the national fire protection association (nfpa) standard manual; the so-called class iii class b flammable substances refer to those substances with a flash point higher than 93.3°c; the flash point of mdi series products tested according to the astm d93 (p.m.c.c) method is 177~277°c.
although the flash point is high, it is still flammable in the presence of oxygen and when exposed to high temperatures and open flames; if the fire is strong, it can cause the closed packaging to explode; heat the material can react strongly with water and release harmful gases.

mainly used in the polymerization reaction of acrylic resin, styrene, abs, processing aid acr, chloroprene, styrene-acrylic latex, styrene-butadiene latex, etc. its function is similar to that of n-dodecyl mercaptan, but its smell is much smaller than that of mercaptan.
(1) in the production of acrylic resin polymerization (such as hammer paint), adding this product can effectively adjust the molecular weight distribution of the resin, making the resin have good leveling properties, uniform viscosity, and bright appearance of the paint film.
(2) in the production of plastic processing aids acr (methacrylate polymerization), adding this product can effectively control the intrinsic viscosity of the product. the methacrylates are polymerized according to process requirements.
(3) provide sulfur components for sulfur tin stabilizers for pvc
(4) molecular weight regulator for polymers

product performance
inv 7000-1 can react off the active carboxyl groups generated after the hydrolysis of the polyester molecular chain, preventing the further progress of the hydrolysis reaction, thereby effectively inhibiting the decline in mechanical properties of the material caused by hydrolysis , greatly extending the service life of the product.
technical advantages
· using the latest synthesis technology, better stability;
· high activity and quick reaction with carboxyl groups;
· high purity, no isocyanate residue;
· superior to similar foreign products and widely used.
typical applications
· inv 7000-1 can be widely used in pu products, such as tpu, cast pu elastomer, pu adhesive, pu coating, pu shoe sole solution, pu microporous elastomer, etc., generally added in an amount of 0.5-2.0 phr, can significantly improve the hydrolysis resistance of the product.
· inv 7000-1 is generally used in polyurethane systems in a molten state, and the processing temperature is not lower than 50°c.
· polyester polyols: the addition amount is 0.5-1.0 phr, which can quickly reduce the acid value of the polyol and improve the hydrolysis resistance of the material.
· tpu: add different amounts of inv 7000-1 to tpu. after a certain aging time, the material will stretchthe retention rate of strength and elongation at break are both much better than the solution without adding inv 7000-1 (70°c boiling test).
storage stability
it can be stored in the original packaging for at least one year under airtight and dry conditions.
packaging specifications
10kg cold-rolled iron drum or 25kg pe-lined paper drum.

solubility/dilution
desmodur® bl 3175 sn generally has good miscibility with the following solvents, but the storage stability of the resulting solution must be tested. desmodur® bl 3175 sn can be diluted with ketones, esters, ether esters and aromatic solvents to a solution of 40% solids (by weight). use a high boiling point aromatic hydrocarbon solvent, such as a mixture of 100# and 150# solvent naphtha to dilute it to a solution with a solid content of 60% (by weight).
do not use aliphatic hydrocarbon solvents.
compatibility
desmodur® bl 3175 sn can generally be used with desmophen® 651, 670, 680, 690, rd 181, a 160, a 265, a 365, a 450 and a 565 in equivalent equivalent proportions (nco/oh=1.0). and desmophen t 1665 miscible. it can also be used with various plasticizers, such as phosphoric acid, sulfonic acid, adipic acid and phthalate esters. however, the resulting mixture must be tested for miscibility.
features/applications
desmodur® bl 3175 sn can be used as a curing agent in color-preserving and weather-resistant one-component polyurethane coatings. adding a catalyst, such as dibutyltin dilaurate (dbtl), can significantly reduce the baking temperature without affecting storage stability. this product can be used in the primer, second coat and topcoat of high-quality industrial decorative paints (electrical appliances, small components, can coatings, coil coatings, etc.) as well as automotive decorative paints. desmodur® bl 3175 can also be used as an additive in traditional baking systems to improve the flexibility and adhesion of the paint film. when desmodur® bl 3175 is mixed with desmophen® 651, the possible baking cycles are:
no catalyst 160℃ 60 minutes
180℃ 15 minutes
200 ℃ 7 minutes
using catalyst 130℃ 60 minutes
150℃ 15 minutes
175℃ 7 minutes
depending on the co-reactant used and the baking time, the paint film may turn yellow when the temperature is above 160°c. when desmodur® bl 3175 is used in coil coating systems, it can be fully cross-linked at the maximum plate temperature of about 241°c and above without adding catalyst dbtl. if 1% dbtl (calculated based on resin solid content) is added, the same effect can be obtained when the maximum plate temperature is approximately 224°c.
safety: hazard identification
it is flammable, may be irritating to skin and mucous membranes, and can easily cause allergies, so special care must be taken when using it. harmful to aquatic life and may have long-term adverse effects on the aquatic environment.
its vapor may cause drowsiness and dizziness.
the safety data sheet (028952) must be strictly adhered to. it includes information on labeling, transportation and storage, as well as information on product use, product safety and ecology.
