Use:

In the industry of adhesive and sealant, petroleum resin plays an important role as tie resin. PR-A series petroleum resins are suitable to the petroleum resin of hot-melt adhesive and contact adhesive. They have good compatibility with SIS, SBS, SEBS, SEPS, natural rubber, synthetic rubber and EVA etc..

The characteristics of LESTAC-A95 , A100, A110 petroleum resin in hot-melt adhesive:

· Good fluidity.

· Good viscosity.

· Excellent ageing resistance.

· Light color.

· Transparent, low odor, low volatile matter.

PRS-A series can be separately used as tie resin in hot-melt adhesive or mixed with other tie resin.

Application field recommended:hot-melt adhesive.

Other use:hot-melt contact adhesive, solvent contact adhesive.

The properties of LESTAC-A100, A110 petroleum resin in solvent Pressure sensitive adhesive:

LESTAC-A100

·Keep the balance of cohesvie strength and peeling strength.

· Excellent ageing resistance.

· Light color.

LESTAC-A110

· Improve peeling strength and cohesvie strength a lot.

· Excellent ageing resistance.

· Light color.

Application field recommended:solvent rubber pressure sensitive adhesive.

Other use:hot-melt adhesive, hot-melt pressure sensitive adhesive.

The characteristics of LESTAC-A95,A110, A110 petroleum resin in hot-melt contact adhesive:

LESTAC-A95

· Has excellent initial viscosity, keeping the balance of initial viscosity and cohesvie strength.

· Comparatively good fluidity.

· Light color.

LESTAC- A100
