Crestomer 1152PA is the ultimate flexible structural adhesive for large-scale composite applications. It is a high-performance, two-part urethane acrylate that delivers over 100% elongation, providing unmatched impact and fatigue resistance. Its non-sag, gap-filling formula is perfect for bonding hulls, decks, and core materials without slumping, while the low-heat cure prevents surface distortion for a flawless finish. With multiple marine certifications, it's the trusted, durable choice for the most demanding bonding jobs.
Crestomer 1152PA is a two part, MEKP activated, pre-accelerated, highly thixotropic structural adhesive based on unsaturated urethane acrylate in a styrene monomer. It is used in many structural composite applications and has excellent adhesion to FRP laminates, core materials, wood and some metals.
Due to its excellent adhesion to a wide range of materials, 1152PA can also be used as a general purpose adhesive. It can be used for bonding diesel tanks, contour joints in FRP components, to build up damaged areas and to bond “green” FRP.
Each kit includes: 1 pail of Crestomer Resin, 1 bottle of the related MEKP Hardener, 1 mixing stick, 1 instruction and product data packet

Surface preparation
Crestomer 1152PA has excellent adhesion to FRP material provided that the surface has been maintained free of dust and grease. This can be guaranteed by the use of proprietary strippable cloths such as peel ply (without lubricant contaminates). If the laminate surface is more than three days old, it is recommended that they are lightly abraded and wiped with acetone or styrene on a lint-free cloth prior to bonding.
Application
Crestomer 1152PA is supplied pre-accelerated. The required hardener is a medium reactivity MEKP catalyst. The catalyst is added at 2% v/w. Crestomer® 1152PA can be applied with a spatula or from a dispensing unit, taking care to keep air entrapment to a minimum. Application should always be carried out at temperatures above 15oC / 59oF. Recommended temperature range for application is between 18oC and 25oC / 64oF - 77oF. The use of additional pigments or fillers is not recommended as they can affect the performance of the adhesive.
For industrial / commercial use only. The user must determine the suitability of a selected adhesive for a given substrate and application. Contact Perigee Direct, or a local Scott Bader representative for questions or assistance with the selection of adhesives for your
use. This product is intended for use by skilled individuals at their own risk. Recommendations contained herein are based on information we believe to be reliable. The properties and strength values are obtained under controlled conditions at the Scott
Bader laboratory.
Storage and shelf life
Crestomer 1152PA should be stored between 2°C and 23°C/ 36°F and 73°F in the original unopened container in a dry well ventilated place. Protect from freezing and direct sunlight. Avoid contact with oxidising agents. Exposure to temperatures outside these conditions will affect shelf life. Ideally containers should be opened only immediately prior to use.
The shelf life for Crestomer products is defined from date of manufacture if stored as recommended. The expiry date is indicated on the product labels.
