Application in Neoprene Adhesive System
PergutWhen used in the neoprene adhesive system, it can increase the original Molecular bond strength (increases bond strength), increases their heat resistance, and enables the production of light-colored, stable adhesives with resin-free formulations. Widely used in DIY, footwear, furniture market.
In addition to this application, in vulcanization Pergut can be added during the process of bonding elastomers to metal or other substances under conditions. This process produces a long-lasting bond and good resistance to high temperatures and weathering. Because of its good chemical resistance and good compatibility with various polymers and resins, Pergut is used in many adhesive systems.

1, high initial strength neoprene contact adhesive
When using low melting point resin In the neoprene adhesive, adding 5-10 equal parts of Pergut (calculated according to the polymer) can effectively improve the initial strength. In general, a medium-viscosity Pergut (eg Pergut S 40 or Pergut S 90) is used. Taking the shoe industry as an example, adding Pergut to the adhesive can shorten the curing time of shoe soles and trim edges. Another example is the bonding of plastic films and panels in the furniture industry. Because the addition of Pergut can prevent the plastic film from falling off the edge.

2, light colored stable neoprene contact adhesive
Neoprene-based adhesive The color of the agent depends on the resin. In resin-free formulations, the pot time is very short. Especially toluene-free sticking solutions. In this case, the addition of Pergut prolongs the pot life while increasing the initial bond strength. This resin-free adhesive has excellent shelf life.

3, neoprene good benefit cost relationship ratio
Increasing ecology and economy Constraints keep the adhesives industry in constant search for an ideal compromise between quality and cost. As we mentioned with neoprene, we can see possibilities – even in toluene-free formulations – to achieve acceptable performance at low cost.

4, rubber and metal bonding
PergutIt has long been used to bond all kinds of elastomers— – such as natural rubber NR, isoprene IR, butyl rubber IIR, styrene-butadiene rubber SBR, ethylene-propylene rubber EPDM, neoprene CR, nitrile rubber NBR or chlorinated polyethylene rubber CM – to metal, such as steel , aluminum, brass, etc. Recommended grades are Pergut S 130 and S 170.
This adhesive can Can also be used in two-layer systems in one-layer systems – mostly in two-layer systems. This is subject to specification requirements for dynamic resistance and corrosion resistance.

��Single-layer systems can also be used in double-layer systems – mostly in double-layer systems. This is subject to specification requirements for dynamic resistance and corrosion resistance.
