Durafine Composite and FRP Mould Release Agent Product Range

EX - LAT SERIES

EX LAT-2, EX LAT-2T

Advanced Formula: Provides a durable, non-transfer film for multiple releases per application, ideal for thermosetting resins like epoxy, polyester, and vinyl ester.
Eco-friendly & Easy to Use: Non-chlorinated solvent blend with low odor, easy application with no need for mixing or shaking.
Long-lasting & Versatile: Compatible with all mould surfaces; minimal mould build-up and long-lasting performance with 4 coats for optimal results.

IN - LAT SERIES

IN-LAT-EPX, IN-LAT-POL

Internal Release Agent.No Additional Treatment Required: Enables easy post-treatment (painting, foaming) on released surfaces without the need for sanding or extra preparation.
Easy Integration: Ready-to-use formulation; simply add to polyester, epoxy, or acrylic resins at a dosage of 0.5-1.5% for optimal results.

LAT-LXTR

Multi-surface protection: LAT-LXTR is a clear, polymeric resin coating designed for use on a variety of surfaces including aluminum, steel, FRP, plastic, and glass, offering protection against UV, water, dirt, and lime.
Easy and effective application: The product is ready-to-use (no mixing required), applies easily with a cotton cloth, and cures at room temperature—two coats are recommended for optimal durability.
Key benefits: Long-lasting, cost-effective, and provides excellent surface protection with a coverage of 20–25 m² per liter and a shelf life of 1 year.

Results After Implementation

KPI	Before Durafine	After Durafine
Mold Cleaning Frequency	Every 3–5 cycles	Every 12–15 cycles
Release Time per Part	~10 min	<4 min
Surface Defects / Rework	Moderate	Reduced by 80%
VOC Exposure	High	Reduced by 60%
Mold Life	~300 cycles	>800 cycles

Operational Impact
The switch to Durafine’s release agent resulted in:

30–50% improvement in mold productivity
Lower scrap rates due to better surface finish and fewer pull marks
Cleaner molds, reducing labor and solvent usage
Enhanced environmental compliance and operator safety

Conclusion
Durafine’s external semi-permanent FRP release agent provided a simple yet highly effective upgrade to molding efficiency and surface quality. With longer intervals between cleanings, faster cycle times, and safer working conditions, this solution enabled a smoother, more scalable composite production process.

Durafine Case Study

Solving Mold Build-Up and Downtime with Durafine Semi-Permanent FRP Release Agent

The Challenge
A leading composites manufacturer specializing in FRP (Fiber-Reinforced Plastic) components faced growing production inefficiencies. Their existing release system—based on conventional wax or semi-permanent agents—was causing:

Frequent mold fouling and build-up after just 3–5 cycles
Inconsistent part release, resulting in surface defects and polishing rework
Excessive downtime for mold cleaning and reapplication
Shortened mold lifespan due to abrasive cleaning methods
Difficulty maintaining compliance with VOC limits in a high-volume shop

These issues led to increased labor costs, production delays, and quality complaints, especially on larger, high-finish composite parts used in automotive and infrastructure applications

The Solution: Durafine External Semi-Permanent Release Agent
To resolve these challenges, the manufacturer implemented Durafine's external semi-permanent release agent, designed for high-performance FRP molding.
Key Features Delivered
✔ Forms a durable, heat-resistant barrier on mold surfaces
✔ Withstands multiple releases (10–15 cycles) before reapplication
✔ Compatible with polyester, vinyl ester, and epoxy systems
✔ Non-transferable—leaves no residue on molded parts
✔ Low-VOC and REACH-compliant, safer for operators and environment
