Polyterpene resin

Piccolyte A 25

Piccolyte A25 polyterpene resin is a low molecular weight, pale, inert resin derived from high-purity alpha-pinene isolated from turpentine.

Key properties

It is used in the agricultural industry as a retention aid and sticker for herbicides and pesticides that are applied to crops and plants, in the adhesives industry for specialty PSAs and in the lubricants industry.

It can improve the low-temperature performance of elastomeric and block copolymer-based adhesives.


  • Retention aid for agricultural chemicals
  • Film-former and fixative agent
  • Pressure-sensitive adhesives with styrenated block copolymers, other rubbers and thermoplastic polymers
  • Lubricants based on polyisobutylene and APAOs.
  • Plasticizer

Not regulated

The copolymer is classified by the EPA as an inert ingredient when it is applied to growing crops and to agricultural commodities after harvest, under 40 CFR 153.125. An exemption from the requirement for a tolerance has been established (Federal Register: May 18, 2005) (Volume 70, Number 95) (Rules and Regulations) (Page 28447­-28452).
