Layers of protection

Our co-extruded surface protective films (SPFs) can be used to protect a wide range of surfaces, particularly screens for electronic devices and appliances, as well as construction materials and other products that need protection.

SPFs consist of multiple layers – skin, core and adhesive. It’s the adhesive layer that enables SPFs to bond with the surface that needs protection, and a typical formulation includes styreneethylene-butylene-styrene copolymer (SEBS), hydrocarbon resin (HCR) and additives.

We also supply modifiers that can be used as HCR in the adhesive layer, to open up properties such as peeling strength improvement at a lower material cost.

Dresinate 91-44WL Rosin SoapRosin ResinDresinate™ 91-44WL rosin soap is a fluid, high solids, aqueous solution of potassium soap of tall oil rosin. It is designed primarily for applications that require soap solutions of as low a water content as practical and of viscosity low enough that it is possible to pump the soap at practical temperatures. It is used as an emulsifier ingredient in solvent cleaners and soluble oils for metal cleaning. Dresinate™ 91-44WL  provides highly stable emulsions over a wide range of water hardness when used in combination with petroleum sulfonates in soluble oil formulations.
  • Dilutible with water and aqueous solutions of alcohols and glycols
  • Provides highly stable emulsions

Permalyn™ 5110-C Synthetic ResinRosin ResinPermalyn™ 5110-C synthetic resin is the pentaerythritol ester of gum rosin. It is produced by a special process that yields a low odor, low acid number resin. It is suggested for use as a modifier for film-formers, elastomers, and waxes in various adhesives and protective coatings where pale color and minimal odor are required.
  • High softening point
  • Low odor
  • Resistant to thermal degradation
  • Very good color stability
  • Wide solubility and compatibility range
Permalyn™ 6110-M Synthetic ResinRosin ResinPermalyn™ 6110-M is a high softening point, light color thermoplastic resin; it is a pentaerythritol ester of gum rosin, specially developed to be used in the Adhesives Industry. The special manufacturing process of this resin allows getting a product, which is highly resistant to oxidation, color retention and has minimum odor.
  • Color retention
  • Excellent thermoplastic resin
  • High oxidation resistance
  • High softening point
  • Light color
  • Minimal odor
Permalyn™ 8120 Rosin EsterRosin ResinPermalyn™ 8120 is a pentaerythritol ester of gum rosin which has been chemically modified to have a ring and ball softening point near 120°C. Permalyn™ 8120 has lower color, better color stability higher heat stability, and higher softening point than typical pentaerythritol rosin esters. It is potentially useful in hot melt adhesive and ink applications where a high softening point is desirable and especially in packaging hot melt adhesives where color and viscosity stability at application temperatures are critical.
  • Excellent heat stability
  • High softening point
  • Low color
  • Superior adhesion
