Pre-Accelerated Thixotropic Resin
Pre-promoted wax-free unsaturated polyester resin designed for hand lay-up and spray-up applications on vertical surfaces. Just add MEKP catalyst at 1–2% and apply — no sagging, no promoter mixing errors.
Product Overview
Pre-accelerated thixotropic unsaturated polyester resin eliminates the need for separate promoter addition on the workshop floor. These wax-free grades incorporate a built-in accelerator and thixotropic agent, allowing laminators to simply add MEKP catalyst at 1–2% by weight and proceed with hand lay-up or spray-up application on vertical and overhead surfaces without sag or run-off.
Common Challenges
Resin sagging and run-off on vertical mold surfaces causes uneven laminate thickness and weak spots
Separate promoter mixing introduces measurement errors and inconsistent cure between batches
Inconsistent gel time across temperature variations causes production delays or premature gelling
Trapped air bubbles in laminates reduce mechanical strength and produce visible surface defects
Our Solution
Aertuo's pre-accelerated thixotropic range includes 25-123APT for general hand lay-up, 25-2504APT for fast-cure spray applications, 25-8200PT for large vertical mold surfaces, and 25-SL2597 for sag-free complex contour laminating. All grades are wax-free and pre-promoted — just add MEKP at 1–2% and laminate with confidence. Consistent gel time and excellent air release ensure void-free, high-quality laminates every time.
