Selecting the right plastic welding rod is one of the most important decisions you can make during a repair or fabrication project. While polypropylene (PP) and polyethylene (PE) are both thermoplastics and may appear similar, they behave differently during welding. Choosing the wrong material can produce a weld that looks acceptable initially but ultimately cracks, Read more…
Bonding plastic can seem straightforward until a joint fails under heat, vibration, moisture, impact, or everyday use. In many cases, the problem is not the adhesive itself—it is selecting a product that does not match the plastic, the service environment, or the performance requirements. There is no universal adhesive that works equally well for every Read more…
When a bond fails on a coated metal assembly, the investigation usually starts with the adhesive, but it should start with the specification. Most failures on coated or lightly contaminated surfaces trace back to epoxy applied to conditions it wasn’t designed to handle cleanly, and fabricators who’ve recognized that pattern aren’t going back to epoxy Read more…
Building a Complete Marine Adhesives, Sealants, and Composites Portfolio Introduction Marine manufacturers, repair yards, and custom boat builders face increasing pressure to deliver higher-quality vessels while controlling labor costs, reducing rework, and improving long-term durability.

Memorial Day is a time to pause, reflect, and honor the men and women who served with courage, sacrifice, and dedication. For Chemical Concepts, this remembrance is also personal. The values that shaped Chemical Concepts began long before the company itself — rooted in the life and service of our founder, C. Kenneth Zelle. At Read more…
Sign fabrication has evolved significantly over the past decade. As designs become more streamlined and materials more advanced, the expectations placed on bonding solutions have increased. Today’s fabricators require adhesives that not only deliver structural integrity but also maintain visual clarity, accommodate material movement, and support efficient production workflows. The Chem-Set™ TrimLok™ Adhesive System represents Read more…
Most customers reach out to a distributor after something has already gone wrong. A bond failure, a product that didn’t hold up in the field, a callback on a job that shipped months ago. Stacy Gettys has spent more than 20 years figuring out how to get ahead of that moment, and Chemical Concepts promoted Read more…
Understanding Integra® Horizon™ Methacrylate Adhesive for Indoor and Outdoor Fabrication Surface fabricators and installers are being asked to do more than ever before. Materials continue to evolve, projects increasingly move outdoors, and expectations for durability, aesthetics, and consistency remain high. At the same time, environmental conditions, from temperature swings to UV exposure, introduce variables that Read more…
Huntingdon Valley, PA, February 11, 2026 — Chemical Concepts has acquired Perigee Direct, a Texas-based supplier of specialty consumables for science and industrial customers, significantly expanding its product portfolio, e-commerce capabilities, and distribution footprint. The acquisition strengthens Chemical Concepts’ leadership in adhesives and specialty chemicals while adding new product categories such as plastic welding equipment, Read more…
Conventional anchor nuts weren’t built for carbon fiber, resins, or thin composite panels. Fixed nut plates concentrate stress and demand perfect hole alignment, while standard floating designs lack the self-locking capability needed for vibration-prone assemblies. Float-Nut is a self-locking floating anchor nut that addresses all three problems, all in a single fastener. This guide covers Read more…
Every undermount sink installation carries the risk of a future callback. When traditional adhesive systems fail, you’re not just replacing a sink—you’re protecting your reputation, maintaining profitability, and ensuring long-term customer satisfaction. This guide explains why Keep-Nut™ mechanical anchors are replacing adhesive-based methods in professional fabrication shops. You’ll see actual strength data, learn the installation Read more…
By Chemical Concepts Category: Heat Resistant / High Temperature Resistant Published: December 13, 2025 High heat adhesives are not all the same. When assemblies face bake cycles, elevated service temperatures, or repeated thermal swings, the wrong adhesive can soften, creep, or fail prematurely. This guide explains how to select a heat resistant adhesive for real Read more…
