Resin For Hardness Coating

Resin For Hardness Coating

 Resin For Hardness Coating, industrial coating produced by this resin has good hardness.

Features:

● Epoxy modified;

● Not neutralized;7-8%neutralizer added during use;

● Water-soluble resin,able to used for grinding;

● Amino baking paint,high gloss,and high hardness;

● Good waterproof and alcohol resistance,applicable to glass paint resin;


Technical Index:

Composition:Water based epoxy modified acrylic resin,cosolvent

Non-Volatile Matter(%):52±1

Appearance:water white to light yellow viscous liquid


Properties:

WL-202 can be infinitely diluted with deionized water before stably stored.The viscosity of the dispersion will increase as the pH value increases.After amino resin is added to the product,its stability is related to PH,i.e.the higher pH,the better stability.


Instructions:

WL-202 resin can be dispersed in water after neutralized by neutralizing agent.After the water based amino resin is used as cross-linking agent for baking at high temperature,the paint film can providethe best cross-inking effect.The recommend cross linking agent is partial methyl etherification melamine formaldehyde resin,such as,Cytec 327,325.Generally the amino resin consumption is about 20-40wt.%of WL-202 consumption.The neutralizing agent is generally N,N-dimethyl ethanolamine and trie thylamine and its consumption is about 7%of WL-202 consumption.In order to achieve better adhesion to glass,silane coupling agent must be added before spraying.The baking temperature and time depend on performance requirement,generally 150-180℃and 20-30 min.


Storage

The product should be stored in a cool,dry and ventilated place.The shelf life is 6 months.The expired product can still be used after passing the inspections.
