Carbodilite

• Waterbone polycarbodiimide resin which contains carbodiimide [ - N=C=N - ] group with hydrophilic segments

• Very safe for use and environment friendly crosslinker (Applicable for VOC regulatory compliance products)

• Wide range of products (Customers can choose the most suitable ones)

What is Carbodilite?

• Green (Safe and environmentally friendly)

• Long pot-life

• Good reactivity with carboxylic acid

• Reactive at room temperature

• Promotes adhesion

• Remains flexibility

• Easy to disperse

• Anti-hydrolysis (for resins containing ester bond)

Reaction of Carbodilite

Carbodiimide groups in CARBODILITE react with carboxylic acids in a base resin (polymer) which forms 3-dimensional networks. This 3-dimensional network structures improve water resistance and solvent resistance property.

Applicable resins

• PUD （Polyurethane dispersion）

• Acrylic emulsion

• Carboxylic acid-modified resins (SBR, NBR latex, etc)

• Water-dispersible polyester

Specification

Usage direction

• Suggested dosage level (CARBODILITE solid) ⇒ ca. 3～7% by total formula

• For faster reaction: Increase curing temperature

• For extending pot-life: Increase pH with neutralizer (ammonia, amine )

*Crosslinking reaction does not progress with neutralizer of hydroxide metal

*Pot life may not be extended in case compound contains glycol-based solvents
