Bonding and fixing
No, most types of adhesive need to be applied at a temperature above 5 degrees Celsius and some adhesives only harden at even higher temperatures.
Yes it is. Because adhesive does not cure at temperatures below 5 degrees we advise that it is kept in small tubes and bottles in a (plastic) bag in the refrigerator. We do not advise using a freezer because some types of adhesive contain water.
No, these types of synthetic materials do not join together. Generally, they are joined at high temperature in industrial processes.
PP = Polypropylene
PE = Polyethylene
PA = Polyamide=Nylon
PTFE = Polytetrafluorethylene
Porous materials can absorb moisture. Some adhesives or sealants contain moisture. If these glues or sealants are used then one of the materials to be joined must always be porous.
Examples of porous materials include: gypsum board, untreated wood, concrete and brick, paper, cardboard, cement, etc.
Examples of non-porous materials include: Treated (primed or painted) wood, concrete and brick, construction boards such as MDF, multiplex and triplex plywood, hard and soft synthetics, polystyrene foam (tempex, EPS, XPS), metal, glass, etc.
The best is a two component epoxy adhesive such as Epoxy 5 minutes. If the pieces fit perfectly then superglue (gel) can also be used. However, epoxy adhesive produces the best adherence and is water and dish-washer proof.
No, this two component epoxy adhesive has a grey colour but does not conduct.
If still wet, most types of adhesive can be removed with acetone. Remove white wood adhesive and wallpaper paste with water.
In general, once adhesive residues have hardened, they can only be removed ‘mechanically’ – in other words, cut away, scrapped off, sanded off, etc.
Silicone Neutral and Silicone Acrylic Universal are neutral, acid-free silicone sealants that do not corrode vulnerable materials.
No, silicone sealant does not adhere well with other materials. Paint also does not adhere to the sealant.
No, the basis for this is a neutral silicone sealant. From a constructional viewpoint, this is the best sealing for your glazing. However, if you do want to paint then Super Sealer Construction is a good alternative.
Yes, all Poly Max® variants are acid free.
Some sorts of sealant contain moisture. These sealants only become transparent when they have dried out completely and all the moisture has been drawn out. Be aware that if the sealant is applied between non-porous materials and/or to cold, damp spots then it can take weeks before the sealant has dried out completely.
No, only sealant types that contain moisture or solvents can shrink somewhat. Various silicone sealants and Poly Max® variants do not shrink.
Extra anti-mould elements are added to the silicone sealants used for bathrooms. As a result, the sealant is usually able to prevent mould growth for a long period of time. However, if ventilation is poor or soap residues remain on the sealant joint for long periods then the special elements can wear off.
Use mildew remover to remove surface mould from the sealant joint.
