Techsil Ltd - RTV Silicones

Techsil specialises in RTV Silicones and other bonding technologies; there are 4 main ranges:

1 Component RTV
Moisture / air curing adhesives, sealants and coatings which cure to a maximum depth of 10mm. Products exhibit adhesion to many surfaces and are available in a wide range of viscosities (flow-ability) and cure systems. Heat Cure RTV has the same properties 1 Component RTV but cures with heat >100°C and not moisture.

2 Component RTV (Industrial)
Intended as potting and encapsulant materials to improve electrical and environmental resistance. These products require the addition of a catalyst to initiate cure which may take place at room temperature or in certain cases can be accelerated with heat.

2 Component RTV (Mould making)
These high tear strength, room temperature cure products are designed to produce flexible moulds directly from original masters. A variety of resins can be poured or injected into the mould to produce a number of replica parts. Two ranges exist: Condensation cure for the giftware, plaster and ceramic industries and Addition cure/polyurethanes for rapid prototyping and composite mouldings.

Pressure Sensitive Adhesives (PSA)
PSA are materials which cure to form a thin section, hard yet flexible silicone resin. The cure can take place at ambient or elevated temperatures depending on the chosen grade. The products typically act to laminate between two surfaces - one of which is usually silicone based. These are ideal adhesives to use where a one component heat cure or RTV product would prove unsuitable. Adheres to most surfaces with very slight pressure. Pressure sensitive adhesives form viscoelastic bonds that are aggressively and permanently tacky, they adhere without the need of more than a finger or hand pressure and require no activation by water, solvent or heat.
 

Techsil offer the...
ITW Devcon range of Epoxy Adhesives, Methacrylate Adhesives, UV Light-Cured Adhesives
ITW Permatex range of Threadlockers, Thread Sealants, Retaining compounds, Gasket Makers and Cyanoacrylates (‘super glues’) and more recently the ThreeBond range of gaskets and structural adhesives

Methacrylates
Provide tough flexible bonds for today’s hard to bond plastics, composites, exotic metals and dissimilar substrates. These adhesives can generally be used without surface preparation.

UV Light Cured Adhesives
These offer the flexibility of unlimited open times plus the productivity of instant cure when exposed to UV light.
