HDI Waterborne WanHua 161

 

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:

  1. Excellent resistance

  2. Long pot life

  3. 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. Store contaminated clothes separately and reuse them after washing. Maintain good hygiene practices.

ABOUT:

Blocked aliphatic HDI-polyisocyanate. To formulate lightfast one-component stoving polyurethane coatings with high themal yellowing resistance; as an additive to improve flexibility and adhesion.

Product Types:

  • HDI

  • PIC

  • Aliphatic polyisocyanate

  • Crosslinkers

  • Polyisocyanate

  • Hardeners

  • Polyisocyanurate

  • Isocyanate

Material:

Coatings, paints & inks

Solventborne, Flexible, Thermally resistant, Elastic

General Characterization:

Desmodur BL 3370 MPA is a blocked aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI).

It is suitable for use in combination with Desmophen® grades to formulate lightfast, one-component stoving polyurethane coatings with high resistance to thermal yellowing; as an additive in conventional stoving coating systems to improve the reactivity, flexibility and adhesion.

Storage Conditions:

Desmodur BL 3370 MPA should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. 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. Recommended storage temperature is 0º-30ºC.
