IPDI Quick drying Evonik T1890E

 

ABOUT:

VESTANAT® T 1890 is a cycloaliphatic polyisocyanate crosslinker with remarkably short curing cycles even at ambient temperatures.

POLYISOCYANATE CROSSLINKERS IN 2K SYSTEMS?

  • Combination with a resin component right before application

  • Reaction starts immediately after mixing the polyisocyanate with the resin component

  • Reaction leads to a 3D network with a high durability

Benefits?

  • Low viscosity

  • Excellent compatibility & high reactivity

  • Durability against environmental impacts

  • UV resistant, lightfast and very good gloss retention

  • First-class chemical resistance

  • High reactivity even at ambient temperature

  • Short curing cycles

Storage and Transportation:

STORAGE: It is recommended to store in a dry and cool area with proper ventilation.

Packaging:

200KG/drum Please fasten the packaging cover as soon as possible after original packaging to prevent the mixing of other substances such as moisture and other substances that may affect the performance of the product. Do not inhale dust, avoid skin and mucous membrane contact. Smoking, eating and drinking are prohibited in the workplace. After work, shower and change clothes.

General Characterization?

Aliphatic polyisocyanate (IPDI trimer).

As the hardener component for lightfast polyurethane coating systems and as an additive resin for alkyd spray coatings.

Storage Conditions?

– Storage in original sealed Covestro container.
– Recommended storage temperature: 0 – 30 °C.
– Protect from moisture, heat and foreign material.
General information: The product is sensitive to moisture. Storage at higher temperatures will result in increase of color and viscosity. Storage at significant lower temperatures will result in solidification. This solidification is reversible by briefly heating the product without adversely affecting the quality of the product.

HDI Waterborne WanHua 160

 

Product Description:

Aquolin 161 is a water dispersible polyisocyanate based on hexamethylene diisocyanate (HDI). In combination with water-borne polyurethane, polyacrylate, etc., it can be used for adhesive products toimprove the resistance to hydrolysis and heat. It also can be used for waterborne coatings. After addition of Aquolin 161, the ready-to-use mixture must be used within the pot life.

Aquolin 161 can be diluted with the solvents, such as propylene glycol methyl ether acetate (PMA), propylene glycol diacetate (PGDA), butyl acetate, etc. Only PU grade solvents (< 0.05% water) should be used and the solvents must be tested in advance by the user to determine suitability.

Product Features:

  • Excellent resistance

  • Long pot life

  • Good gloss and building up

Storage:

The product should be stored in dry conditions above 5°C and below 35°C with the integrity of the packaging, and prevent direct sunlight. The validity of this product is for 12 months, performance assessment is recommended before use after shelf life. The product should be protected from freezing during storage. Water dispersible polyisocyanates are very moisture-sensitive and react with water to form carbon dioxide and insoluble ureas. The generation of carbon dioxide can lead to dangerous increase s in pressure. The containers must always be kept tightly closed and the access of water in all forms must be prevented. It is suggested to use up once the package is open.

Packaging:

200KG/drum Please fasten the packaging cover as soon as possible after original packaging to prevent the mixing of other substances such as moisture and other substances that may affect the performance of the product. Do not inhale dust, avoid skin and mucous membrane contact. Smoking, eating and drinking are prohibited in the workplace. After work, shower and change clothes.
