船舶和防腐涂料

关于船舶和仿佛涂料最常见的问题及回答

Can you recommend a suitable rheology additive for a xylene based alkyd paint?

What additives do you recommend to stabilyze Zinc dust in solvent-borne system? The additives should keep zinc from agglomerating but not insulate the particles from making good electrical contact.

Which dispersant agent is your recommendation for fluorocarbon resins? I am interest in all kind of pigments.

I am working on a TiO2 pigmented solvent free epoxy. I have found severe loss of hiding while curing. TiO2 disperes fairly well in the epoxy, and even better in the amine curing agent without dispersant, but it leads to loss of hiding. What can I do?

We are developing 2 pack polyurethane coatings. Sometimes, the cured coating shows flooding and floating. The problem is worse, when the coating colours are dark: blue, grey, green. Can you give us any suggestion?

I am working on an epoxy system, which is highly filled and I run into the following issue: It it very high viscous, but however the pigments and fillers settle. What can I do?

I need to disperse a high load of fumed-silica into a liquid epoxy resin to thicken the binder and a rheology agent to stabilize the viscosity, whithout losing good flow properties while processing. Which BYK additives can I use to meet the requirements?

We are developing 2 pack waterborne epoxy anti-corrosion coatings. Now in my lab experience, pinholes are always observed in the coating film. Do you have any ideas? What kind of surface additives do I have to use?

What flame retardent additives can you recommend for my intumescent coating?

We are looking for an additive which prevents our heavy duty epoxy coating from sagging.

Our target is to formulate a Polayaspartics top coat, which has a smooth, dull surface. How can we achieve this?

We are working on different epoxy top coats for water ballast tanks and coatings. Do you have additives to improve the clenability, or to decrease the dirt pickup?

What HAPS (hazardous air pollutants) free dispersing agent(s) would you recommend for an 80-90 NVV system? Pigments are dispersed in the 100 epoxy resins with MAK as solvent. The dispersing agents also need to be able to lower viscosity of grinding paste.

I am looking for a rheology additive for waterbrone anti corrosive primer / direct to metal coating. Could you advise some of your products, which provide sag resistance and do not increase water sensitivity?

Which is the best wetting and dispersing additive for waterborne anti-corrosive coatings? Most of the additive I tested had a negative influence on water absorbtion and corrosion protection.

Do you have a rheology additive that will work in a amine grind? All rheology additives I tried are either not working at all or reacting and too thick.

Do you have an additive for antifouling which can replace copper?

I have a gelletion on epoxy pigment paste during storage. Especially on red and blue colors. What could be the reason and how i can solve it?
