Eastman Olefin Resin Piccotac

Features Of Eastman Olefin Resin Piccotac

1. Enhanced Compatibility: Seamlessly integrates with block copolymers (SIS/SBS/SEBS) and diverse polymer systems for flexible formulation Optimized Processing: Low molecular weight and narrow molecular weight distribution (MWD) ensure superior flow properties and low-temperature performance

2. Durability & Stability: Antioxidant stabilization extends shelf life, reduces thermal degradation, and minimizes yellowing for light-colored applications

3. Eco-Safe Formulation: Low VOC, compliant with food-contact and medical standards, ideal for hygiene-sensitive products

4. Balanced Adhesion: Enhances both initial tack and long-term cohesion for pressure-sensitive and hot-melt adhesives

Typical Applications Of Eastman Olefin Resin Piccotac

1. Pressure-Sensitive Adhesives (PSAs): Labels, medical tapes, and industrial tapes requiring high peel strength and aging resistance

2. Hot-Melt Adhesives (HMAs): Carton sealing, footwear bonding, and hygiene product assembly (e.g., diapers) with fast curing and low odor

3. Rubber & Elastomer Modification: Tire compounding, sealants, and automotive components for improved tack and weather resistance

4. Industrial & Electronics: Wire harness mounting, waterproof coatings, and electronics assembly adhesives

Eastman Olefin Resin Piccotac – Frequently Asked Questions (FAQ)

Q1: What is the primary function of Eastman Olefin Resin Piccotac in adhesive and coating formulations?

A: Piccotac functions primarily as a tackifier, enhancing initial adhesion (tack), peel strength, and shear resistance in hot-melt, solvent-based, and water-based adhesive systems. It improves compatibility with polyolefin-based polymers and contributes to balanced performance across temperature ranges.

Q2: Is Piccotac suitable for use in food-contact adhesives?

A: Yes—Piccotac resins are designed for use in adhesive systems intended for indirect food contact applications, subject to compliance with applicable regional regulatory frameworks and final formulation evaluation. End-use compliance depends on full system assessment, including substrate, processing conditions, and migration behavior.

Q3: How does Piccotac compare to rosin ester or terpene-based tackifiers in polyolefin-rich systems?

A: Piccotac offers superior compatibility and thermal stability in polyolefin-dominated formulations compared to many rosin or terpene derivatives. Its non-polar, saturated hydrocarbon structure minimizes discoloration and oxidative degradation, supporting longer pot life and improved high-temperature performance.

Q4: What solvents are commonly used to dissolve Piccotac for solvent-borne adhesive applications?

A: Piccotac dissolves readily in aliphatic and aromatic hydrocarbons (e.g., toluene, xylene, VM&P naphtha) and chlorinated solvents. It has limited solubility in polar solvents such as alcohols or ketones, so solvent selection should align with resin polarity and overall formulation polarity requirements.
