Hardener for PU Glue and Synthetic Rubber Adhesive

Product Detail

Introduction

Hardener HN-RFE is “Aromatic Polyisocyanate” compound. It has higher performance of cross-linking and vulcanization. It is widely used for curing of natural rubber, synthetic tuber or other adhesives, improve property of bonding strength, heat and water resistance etc.

 

Model: HN- RFE

Application

The hardener can increase the initial bonding strength, heat resistance, yellowing-resistance and water-proof ability of the adhesive.

Usage

1. Formulation ratio (by weight):

adhesive	Humidity	1kg	2kg	3kg	4kg	5kg
Hardener	Below 80%	30g	60g	90g	120g	150g
	80-90%	40g	80g	120g	160g	200g
	Above 90%	50g	100g	150g	200g	250g




2. Add the hardener into the adhesive, and stir it to mixing evenly.

3. Increase adding amount in rainy day or higher moisture.

4. When mixed with hardener, use it within pot life.

5. Opened containers should be closed to prevent curing or inefficiency of Hardener.
