Briefing

RTV Silicone Rubber for mould making is a material of mould making, it's suitable for stone, gypsum, resin prodcuts mould m

Detailed

RTV Silicone Rubber ---- Mould Making Silicone Rubber

Hong Ye RTV silicone rubber is used to make moulds for concrete, gypsum, resin, PU, polymer products.

RTV silicone rubber will help make perfect moulds for you with good performance as follows:

Good characteristics of easy-operation
Light viscosity and good flowability
Low shrinkage
Favorable tension
No deformation
Favorable hardness
High temperature resistance, acid and alkali-resistance and ageing resistance

Features of RTV silicone rubber:

Two-parts, flowable liquid silicon & curing agent.
It gets cured at room temperature 25 0C within 5-7 hours.
An exceptional fluidity and good operability, easy to be demolded.
Good tensile strength and tear strength, low shrinkage.

Datasheet of RTV silicone rubber

Model	Color	Mixing ratio	Pot life (mins)	Demouled time (hrs)	Hardness(A0)	Tensile-strength (kgf/cm2)	Tear-strength kgf/cm)	Viscosity (cps)	Elongation (%)
625	white	3%-5%	30	5-6	25±2	35±2	20±2	19000±3000	≥400
E642	translucent	1:1	30	5-6	40±2	70±2	17±2	7800±200	≥320

Notice: 625 is condensation cure RTV silicone rubber, E642 is platinum cure RTV silicone rubber.

FAQS of RTV silicone rubber

1. Why is the tear strength of the silicone mold weak?

In order to reduce the viscosity of silicone rubber and pursue a good quality, you may add a lot of silicone oil into the silicon rubber when making molds. In fact, it might have just the opposite effect. The tension and the tear strength will be reduced badly with the addition of silicon oil. And the silicon molds will be in a weak and flimsy manner.

2. Why isn’t the silicon mold acid & alkali and aging resistant?

It is due to the addition of the silicon oil. Normally we do not advise our customers to add any silicon oil into the silicon rubber. If it is necessary, the ratio must be 5%-10%.
