HEXA(H)-80

Description

This HEXA(H)-80 is a kind of slow-curing alkaline accelerator. The curing rate is slow, and the degree of crosslinking is very high. Thiazoles, sulfenamides, thiurams, and dithiocarbamate accelerators can activate and secondarily accelerate rubber compounds containing HEXA. As a formaldehyde donor, it is especially suitable for bonding rubber to metal or steel cord. This product is not a bloom.

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 thiuram accelerator; 2.0-3.5 phr with sulfur.

Application

Formaldehyde donor in a white system, rubber roller, thick-wall products, bright and transparent products.
