Yes- as most products can settle out.
Please see our comprehensive list of FAQ’s below. If the qustions you have are not covered in the FAQ’s , please feel free to email us [email protected] or use our contact page .
- NO. you must ensure the piece is thoroughly dried and all solvents have evaporated off. - See more at: http://www.jacobsonchemicals.co.uk/jcl/faq/aerosols-release-agents-faq/#sthash.g7uTy0cT.dpuf
- Two or three coats are recommended
- Yes wax based is best: see J Wax
- PVC 322 Vinyl Strippable Coating, then coat with J Wax for release. -
- Poly 90
- Wax based releases: see J Wax/mirrorglaze
- J Wax or Mirrorglaze
- A2H2
- Either a wax or petroleum jelly based release: see J Wax liquid/aerosol or J Lube -
- Yes from time to time, phone for current availability -
- Yes DPS 20 melting pots and Vacuum units are available at a competitive daily rate. -
- Contact us and we can arrange it for you
- We can supply it in cubed, blocks or slabs, in 25kg packs. -
- Yes, this is why this product has an advantage over other moulding materials. You can remelt 20% with fresh material. -
- Yes, bubbles are caused by the expansion of air from the master when the molten product comes into contact with it. Sealing the master will prevent this from happening -
- It is designed specifically for moulding plaster/stone and concrete articles at low cost. -
- Melters are made for this purpose and we are pleased to be able to supply them from 2.5li to 100 li. We also can hire them out per day. -
- Check out our User Guide in the Technical Advice section. -
- Fillite would be the recommended bulking agent for this -
- Either directly coat the mould, or mix with the first coat of resin. Another bulking agent can be used to increase the weight if needed.
- A general- purpose inert filler such as talc can be added in a 50: 50 ratio
- NO, the pigments are dispersed in the correct base for each type of product, results can not be guaranteed or even expected if the wrong type is utilised -
- Silicone - up to 10% maximum Polyester - up to 5% maximum Polyurethane - up to 5% maximum Latex - up to 5 % maximum -
- Even after vacuuming, once the resin is poured into the mould it can extract air from the mould itself, particularly as the temperature rises as it starts to cure (the exotherm increases). We would always suggest that the way to avoid this is to preheat the mould for 1-2hours at 40-50 degrees C. -
- In thinner sections, they can be brittle: this would generally be the result of poor mixing or wrong ratio. This can be counteracted to some degree by post curing, which will improve the properties -
- Most need to be used at room temp)25 degrees C), but there are some that require an elevated temperature for curing. -
- There are several criteria you can sort by: Thin/thick section casting Quick setting Filled resins Water white/clear castings Heat resistance High impact resistance Thermoplastic appearance Room temperature curing -
- Try Super Sculpey: it can be baked and thus remain hard
- Yes, but if it has been liquefied, there are limitations as to the number of times.
- 135 degrees C.
- Plastiline:- it was specifically developed for this purpose unlike other products with similar names!
- Paddle rollers, masking tape, brushes are available- see the full range
- Try Super Elasticlay; it remains flexible even after baking
- Yes - use Sculpey diluent.
- All are suitable
- M31 is ideal
- We recommend Silicone RTV C45 + Cat 45B
- French chalk is recommended -
- BM5135, BM5185, BM5460, BM5030 BM5166, BM5172, BM5108, BM5272, BM5440, BM5470, BM5055 -
- Foam board, ML200 ML450 BM5120
- Yes: see our range of polyurethane pigments
- Yes see J Foam 3106 and J Foam 3087
- Check each Technical Specification for skinning properties
- Density can be varied by increasing/decreasing the pressure in the mould.
- We would always recommend small vent holes are a requisite part of the mould. Pe
- A GRP mould generally will work best: see our range of polyester resins etc.
- We would recommend J Wax in either liquid or aerosol, depending on surface coverage required.
- Each foam will vary : please check the Technical Data for each foam to ensure the recommended mix is obtained.
- We would not recommend it as the foams properties will be impaired -
