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.
