Description

This HEXA for Rubber Curing is a kind of slow curing accelerator of alkaline. The curing rate is slow, and the degree of crosslinking is very high. Thiazoles, sulfenamides, thiurams, and dithiocarbamate accelerators can activate and secondarily accelerate on the rubber compounds containing HEXA. As a formaldehyde donor with resorcinol is especially suitable for bonding of rubber and metal or steel cord. This product is not blooming.

Function

JXBHgran HEXA-80 is a slow accelerator that can be used with thiazoles, sulfenamides, dithiocarbamates, and thiuram accelerators. At the same time, HEXA is a formaldehyde donor that combines with JXBHgran R-80 and silica to increase the bonding strength between rubber and steel cords.

Dosage

Formaldehyde donor: 1.0-2 phr, and 2.0-2.5 phr with R-80.

As accelerator: primary accelerator: 0.6-0.8 phr, and 3.0-4.0 phr with sulfur.

Second accelerator: 0.1-0.35 phr and 0.25-1.0 phr thiazole or thiurams accelerator 2.0-3.5 phr with sulfur.

Application

Formaldehyde donor in a white system, Rubber roller, Thick wall products, Bright and transparent products.
