In the competitive world of window and door manufacturing, choosing the right adhesive partner can have a profound impact on your business. Environmental regulations grow stricter by the year, customers demand more sustainable solutions, and production efficiency becomes increasingly important. In this landscape, your choice of adhesive technology can be a critical competitive advantage. So, what exactly should you expect from an adhesive partner?
A reliable window and door adhesive partner goes beyond just supplying products. Technical support, testing services, and tailored solutions for smoother production should all be part of the package.
Here are 10 benefits that the right adhesive partner can bring to your window and door manufacturing:
1. Unrivaled joint strength with D4-class PVAc adhesives
When talking about demanding applications such as finger jointing and face lamination, it’s crucial that window and exterior door adhesives are designed for maximum joint strength. For example, Kiilto’s adhesives undergo rigorous testing for breaking strength, ensuring they can endure diverse weather conditions and stress in any situation.
2. Superior durability in extreme weather conditions
Adhesives with D4 water resistance and high WATT 91 heat resistance strength are essential for windows and doors exposed to harsh conditions. Heat resistance can’t be overlooked, as dark-colored exterior doors heat up significantly in direct sunlight, and sun-facing windows can get much hotter than the surrounding air. Kiilto’s adhesives are tested to withstand these temperature fluctuations, which place significant stress on adhesive bonds.
3. Sustainable solutions for future-proof production
Adopting window and door adhesives that deliver both high performance and environmental responsibility is key to ensuring long-term, sustainable production. The brand-new Kiilto Pro WRD 4700 UV is a prime example of this balance. This D4-class PVAc adhesive is especially ideal for finger-jointing applications, combining market-leading joint strength, premium weather resistance and environmental responsibility. With 8% bio-based content through mass balance calculation, it stands out as one of the first bio-based D4 adhesives on the market.
4. Lower carbon footprint
As climate change concerns intensify, companies face increasing pressure to reduce carbon emissions. Environmental Product Declarations (EPDs) are commonly required to document the carbon footprint of building materials. Even though adhesives make up only a small portion of a window’s or door’s total composition, choosing bio-based adhesives means less reliance on fossil raw materials and contributes to lower carbon emissions throughout the product lifecycle.
5. Safer work environments
Water-based PVAc adhesives offer a safer alternative to traditional formaldehyde-containing adhesives. As regulations around formaldehyde become stricter due to health concerns, the low-emission properties of water-based window and door adhesives ensure a healthier production environment without compromising on quality or durability.
At Kiilto, our goal is always to achieve an M1 rating, which certifies that our materials meet the highest emissions standards for indoor air quality. This is especially important for production workers who handle adhesives daily.
6. Improved production workflow
The best window and door adhesives improve overall production efficiency. Kiilto’s adhesives do this by reducing pressing times, optimizing adhesive quantities, minimizing waste, and enabling precise application. For quality control purposes, our Kiilto Pro WRD 4700 UV adhesive includes a UV marker for easy verification of adhesive placement using UV light. This can be done either manually or with automated machine vision.
7. Proven performance through testing
Make sure your window and door adhesive partner conducts rigorous testing to ensure the performance of their products in real-life conditions. At Kiilto, our adhesives are thoroughly tested in our own laboratories and certified by accredited external laboratories.
We conduct delamination tests with actual production pieces from customers—not just with laboratory samples. These tests ensure the adhesive maintains its strength even as the wood expands and contracts through repeated exposure to moisture and drying. We also offer standardized testing services for our customers who may not have the equipment or resources to conduct these specialized tests themselves.
8. Custom solutions
The right adhesive partner understands your specific challenges and is dedicated to providing tailored solutions. For example, when a client needed a window and door adhesive that could achieve higher break test strength than existing options, our R&D team got to work. Through meticulous development and extensive testing, we developed our Kiilto Pro WRD 4700 UV adhesive that not only met but exceeded these demands. We continuously work closely with our customers to ensure that every product solves real-life challenges.
9. Industry-specific expertise
Every manufacturing process is unique. That’s why you need window and door adhesives that are specifically designed for different materials, machine types, and production techniques. Kiilto’s comprehensive range of bonding solutions is designed for different finger-jointing and lamella bonding applications, helping you to find just the right solution from our vast selection.
10. Comprehensive technical support
Last but definitely not least on our list is technical support. At Kiilto, our deep understanding of varying manufacturing environments allows us to assist customers in optimising their processes. Whether you need help with determining optimal adhesive quantities, improving production speed, or conducting standardized strength tests, our dedicated technical team is there to support you every step of the way.
