Frequently Asked Questions

QCan a fluorinated surface be coated?


There are many materials with fluorine properties.

Teflon is very difficult to stick to. A strong alkaline (water-soluble Calcium Oxide Liquid) procedure or Plasma procedure is required before applying an adhesive.

For these situations, We recommend you consult a professional.

QDo you have high-heat resistant adhesives?
AThe answer depends on the amount of heat you want to resist. Polyimide has the highest heat resistance of all organic adhesive series, resisting up to 300˚C. If you need resistances higher than 300˚C, please use non-organic based adhesives.
QIs it possible to glue underwater?
AEpoxy adhesives can be used on wet surfaces. This type of product is called Water Bond, indicating that it is able to be used on wet surfaces.
QWhat are the recommended adhesives for metal to concrete? and anything I need to know before applying.

AUse type one adhesives: Sharpie Modified Series, Sharpie Silicone Series, Sharpie Urethane Series. Because there is a difference in expansion rate between metal and reinforced concrete, you should use the same strength when peeling. Pay attention to the application—make sure you use the right amount. We recommend using a primer before applying the adhesive.
QWhat are the recommended adhesives for nylon to wood? and things I need to know before applying.
AWe recommend the epoxy based series. Using sandpaper to sand the surface of nylon can improve the adhesion strength. The wood used should be dry, but not too dry. Being either too dry or too damp both have negative effects on adhesion.
QI want to replace solvent based adhesives with water based adhesives, what should I know about water based adhesives?

ABecause of environmental and safety issues, water based adhesives will replace solvent based adhesives eventually. Currently, water based adhesives are not yet the perfect substitute. Because of reduced volatilizing speed, construction workers need to watch the time and monitor the temperature changes. Additionally, water based adhesives freeze at a low temperature. They also are not as water resistant as solvent based adhesives. We recommend examination before application.
QAre there adhesives that have no negative effect on health?
AThis is a hard question to answer. Even Gelatin, a natural adhesive, has negative health effects. It is said that there is no completely non-polluting adhesive. Because there are seldom health problems that correspond to adhesive materials, it is safe to say that adhesives used in the modern day do not cause health problems.
Nevertheless, formalin, previously a candidate for causing Sick House Syndrome, was forbidden in 2003 by the Japanese building law. Likewise, other harmful substances such as toluene and xylene are being used less and less. The entire sealing and construction industry is trying to improve the situation.
