Frequently Asked Questions:
Glue 123 "Mitreapel"
Mitrapel Polyurethane foam spray
Glue 123 "Mitreapel"
What parts does 123 mitrapel glue include?
This product usually comes in two parts: * Cyanoacrylate liquid: the same main glue that has immediate adhesive properties. * Activator spray: makes the glue dry and harden in a fraction of a second (usually 3 to 5 seconds).
Is mitraple suitable for gluing everything?
no Mitraple is excellent for the following materials: * Wood and MDF (very common in the cabinet making industry) * Metals, rubber and ceramics * Stone and some hard plastics Warning: It is not a good choice for parts that need flexibility (such as fabric or soft leather) or polyethylene and Teflon surfaces and may cause brittleness or lack of adhesion.
How can I increase its adhesion?
* Cleaning: before applying glue, clean the surfaces from dust, grease and moisture. * Amount of glue: Do not use too much liquid glue; A thin layer is enough. A large amount of glue not only does not increase the strength, but also causes the drying time to be longer and the edges of the work to whiten.
What should we do if the glue gets on our hands or clothes?
* On the skin: do not try to force the glue under any circumstances. Wash the area with warm water and soap. Acetone can dissolve the glue, but be careful of skin sensitivities. If the glue spills on sensitive areas such as eyes, see a doctor immediately. * On clothes: It is usually removed with acetone, but be sure to test on a small part of the fabric first so that the color of the clothes does not change.
What is the cause of whiteness around the glued area?
This happens due to the rapid "evaporation" of the glue (the so-called blooming phenomenon). If you apply the activator (spray) from a very close distance or use a large amount of glue, its solvents will escape as vapor and settle on the surface in the form of white powder. Solution: spray from a distance of 20 cm and save on the use of glue.
What is the expiration date of glue 123?
Mitrapel adhesives usually have a good shelf life if the lid of the container is not opened. But after opening, due to the reaction with air humidity, they gradually thicken. * Note: Always close the lid of the container tightly and store it in a dry and cool place (away from direct sunlight).
What is the difference between different models of Mitraple?
Mitrapel is available in different models and sizes, the main difference of which is the glue concentration: * Thick (jelly) models: they are better for uneven surfaces or porous wood because they do not penetrate into the surface and fill the empty space. * Thin models: they are more suitable for gluing parts that are fully mated (flat surfaces) and penetrate faster.
Mitrapel Polyurethane foam spray
What is Mitrapel foam spray used for?
This foam expands and hardens in the vicinity of air humidity and has the following uses: * Sealing: filling the gaps between the door and window frames with the wall. * Insulation: Thermal and sound insulation for utility pipes and ducts. * Filling: Filling large gaps in walls, ceilings and holes made for electrical and water pipes. * Installation: helping to stabilize the frame of anti-theft doors and double-glazed windows.
What is the difference between Gankhor foam and hose foam?
* Foam hose: Comes with a plastic straw. It is suitable for small and domestic work and does not require additional tools. * Gun-eating foam: requires a "special foam gun". Its advantage is that you can precisely adjust the speed of foam output, it has less waste and is much more economical and cleaner for professional and high-volume work.
Why does the foam puff up after spraying?
Polyurethane foams have expansion properties. As the foam comes out of the spray, it chemically reacts with the moisture in the air and expands. * Important note: always fill the cavity only to 40-50% of the foam, because after a few minutes the volume of the foam will double by 2-3 times. If you overfill, excess foam will come out and you'll have to cut it off after it dries.
How long does it take for the foam to dry?
* Initial fixation: usually 15 to 30 minutes (after this time you can cut the excess foam with a cutter). * Complete hardening: depending on the temperature and humidity of the environment, it takes between 12 and 24 hours to reach the final strength.
How to remove dried foam from surfaces?
* Before drying: you can use "foam cleaner" spray (for Mitrapel) or acetone to clean the wet foam. * After drying: there is no effective chemical solvent that does not damage the surface. The only way is mechanical shaving (with a cutter or sander). So be careful to cover the work area with paper tape before spraying.
Is this foam resistant to water and sun?
* Water: Mitrapel foam is resistant to moisture and absorbs water penetration. * Sun (UV rays): Foams are extremely sensitive to direct sunlight. If the foam is exposed to direct sunlight, it will gradually change color and become powder. Be sure to cover it with paint, plaster or putty after drying.
