Description
CTA 16002 pre powder coat seam sealer is a high temperature white sealant adhesive, designed to cope with powder coat temperatures. These are readily available from us here in the UK and from our key distributors around the world. This unique product has been designed to air dry and be passed through the oven bake cycle, whilst simultaneously the powder is being applied (i.e. one pass through the powder coat oven). The advanced technology of these products are moisture curing with the added advantage of being solvent free. Please note that this product no longer requires heat curing so is very versatile. They can also be put back through the oven multiple times if required.
Pre powder coat seam sealer 16002 has been designed to cope with a typical paint bake cycle of around 45 minutes at 180°C. However, seam sealers will cope with up 200°C / 392°F short term.
Many of our industrial customers have found that the high temperature capabilities of these products have enabled the reduction of welding and process time within the factory, therefore saving time and money.
If a pre-treatment process is currently used, 16002 must be fully cured beforehand. The seam sealers need to be fully cured prior to entering the oven.
Laboratory tested for suitability:
16002 up to 180°C (short term 200°C / 392°F up to 45mins)
- Customer approval at the fore mentioned temperatures
- Once air dried, just a single pass through the oven required.
- No pre-baking required
- Always ensure sealant is fully cured prior to any pre treatments or degreasing processes.
- Average skin over time is 20 minutes
- White in colour

Description of 16002 pre powder coat seam sealer – white
CTA 16002 is a high temperature, moisture curing solvent free adhesive. It was designed specifically to cope with pre treatment or degreasers, which are often applied to parts prior to being put through an oven bake cycle.
Our extensive tests proved that 16002 powder coat adhesive seam sealer once put in place and air dried, it is then possible to spray degreasers prior to being put through the oven bake cycle.
- This adhesive holds parts together whilst being pre treated and put through the powder coat oven cycle at 180°C for up to 45 minutes.
- We recommend you check the temperature of your oven and simply turn it down for great results.
- Non Hazardous, Environmentally friendly, safe to use
- Unregulated making shipping costs low
- CTA 16002 is a 290ml cartridge and white in colour.
Application of pre powder coat seam sealer 16002 white:
This adhesive seals joint seams and holds parts together when put through the powder coat over cycle at 180°C (short term 200°C up to 45 minutes).
Uses:
CTA 16002 is often used by paint and powder companies when preparing aluminium panels for automotive, construction and manufacturing industries in general. Panels can be bonded together with this adhesive more quickly than using traditional methods. Stainless steel stiffeners can be confidently bonded to panels prior to paint cycles within the cladding and commercial façade industry.
Above is an example of a typical pre-powder coat seam sealer application. You can read more about it in our case study here.
High temperature sealants are a versatile and more attractive solution to many costly production processes.

How to apply Pre Powder Coat Seam Sealer Adhesive 16002
- Degreasers can be used prior-to or post, the curing process. However, it is very important that the product is fully cured before degreasing, otherwise you may experience bubbling (During the curing process the moisture/degreaser potentially may bubble out during the heating process).
- Surface preparation is key to any bonding application. Use a good degreaser with a high alcohol content such as CTA 100. CTA 100 will flash off and does not leave a residue.
NB: An example of a bad cleaner would be White Spirits as this would leave a greasy film.
- CTA Powder Coat Adhesive/Sealant is an “atmospheric” air drying / moisture curing product, meaning the tiny bit of moisture in the atmosphere. Our product draws atmospheric moisture into the applied bead for a given time period depending on depth of bead/gap fill (During that curing process no other liquid or degreasers can be put onto the product).
- Full cure will depend on the thickness of the bead, we currently have customers bonding in a variety of bead thickness, we have yet to come across the maximum gap fill capability, the average bead thickness is 1-3mm and will take up to 24 hours. As this product is air drying, the thicker the bead the longer the cure time, prior to oven entry. When fully cured the product is a firm sealant that you may be able to make indentations in such as a fingernail. i.e. medium/firm shore hardness. Method of application is the same as any other calk/sealant and is a thixotropic paste.
- Check the temperature of the oven, our products will cope with up to 190°C (374°F) (please do not over bake, just one pass through the oven bake cycle whilst powder is being baked on)
- Once cured your part can pass through the oven as normal.
- When testing, we would suggest you put a separate bead on something else and cut in half to check if ready.
Before dispensing, ensure that surfaces are clean, dry and free of any dirt, dust and grease. For the best results, we recommend using CTA IPA Cleaner Degreaser.
The ideal application temperature is between 15 – 25°C.

Both products bond the same component types and are used in the same industries. Why not purchase one of our trial kits and try both products to see which one works best for your application?
