It is also recommended in the preparation of the let-downs.
Both DELTA-SC 2034 and DELTA-SC 2030 are recommended when surface slip is required. DELTA-SC 2034 will exhibit the best slip performance.
DELTA-DC 3590 (pH-independent) is a new generation additive used to manufacture resin-free or resin-containing pigment concentrates with a pigment level of minimum 30% (depending on pigment type). The pigments are extremely well dispersed and stabilized providing concentrates than can be easily incorporated into various binders without any difficulty.
DELTA-DC 3590 has extremely good water-resistance properties.
DELTA-S 5225 and DELTA-S 5220 (multifunctional additives) can be also good candidates for economical formulations.
DELTA-DC 4071 shows excellent rheology when used in the formulation to prevent settling and sedimentation.
DELTA-DC 4211, DELTA-DC 4212 and DELTA-DC 4010 M are recommended for both SMC (Sheet molding compounds) and BMC (Bulk molding compounds).
All these 3 dispersion control additives improve the dispersing/grinding process of fillers and extenders.
Through a better wetting and a more homogeneous distribution of the fillers, a strong viscosity reduction is obtained. This results in an improvement of the physical properties like the impact resistance, especially in systems filled with Al(OH)3.
DELTA-FC 1020, DELTA-FC 1720 and DELTA-FC 1723 are widely used as air-release agents in unsaturated polyester systems. Their rapid defoaming performance makes them most suitable for applications with high layer thickness.
DELTA-SC 2033 is a compatible silicone-based surface control additive, which lowers the surface tension and improves flow and leveling. Given the fact that it may stabilize foam in the gelcoats, only low addition levels are recommended.
DELTA-DC 3047 is the most suitable dispersion control additive for gelcoats exhibiting excellent deflocculation and stability performance. It can also be used to make pigment concentrates based on UPE.
DELTA-DC 4211 is also a good alternative if no organic pigments are involved in the final formulation.
The silicone-free DELTA-FC 1020 and DELTA-FC 1720 are widely used as foam control additives in putties.
DELTA-DC 4211 and DELTA-DC 4010 M are the most suitable dispersion control additives for putties exhibiting excellent de-flocculation and stability performance.
DELTA-DC 4040 could be also used.
