Microballoons are clearly the better choice for a variety of reasons such as chemical composition, consistency in size and strength-to-weight ratio. This all imparts better behavior like spreadability, sanding and fairing qualities, shrinkage, adhesion and overall strength. Microballoonʼs spherical structural is ubiquitously demonstrated in physics and nature as the strongest structure per given area. Microballoons “nest” into microscopic voids and give good mechanical tooth at the same time reducing polymer shrinkage and increasing structural stability. Mechanically, the compound sands very nicely and is unequaled as a primer substrate for further laminations or final paint. The fact that this is a vey low exothermic resin, hence low-shrinkage resin make it an outstanding choice for a potting compound and structural base for leash plugs, fin boxes or plugs. A very common mistake is made when utilizing leftover laminating resin for use in potting fin plugs, boxes or leash plugs. Laminating resin has a much “hotter” promoter system that is designed to cure resin in thin films. Larger masses of resin, like that in cavities for plugs or boxes allow the resin to exotherm and shrink, pulling away from the walls of the cavity. Microlite is also is an excellent choice where compressive strength is of importance such as deck foundations. This putty exhibits a prolonged “B-Stage” whereby it remains firm and rubber-like for a good 10 minutes allowing the user to cleave off excess material and make for an easier final sanding. In general, mechanical properties are good. It can be sanded, drilled and tapped and is an excellent substrate for painting. Polyester putties have long been used in the automotive industry as body fillers and the microballoons act like miniature ball bearings that roll over each other, imparting spreadability. They increase the productʼs overall durability and mechanical tooth as well as corrosion resistance. Conveniently, curing commences within 30 seconds of exposure to mid-day sunshine in nonpolar latitudes. Ambient temperatures as low as -20°F or as high as 120°F have little effect on cure time or physical properties of Solarez. Another phenomenon attributed to UV curing is the ability to start and stop the reaction when so desired. You may cure the resin for approximately one minute until it has reached “B-Stage” (when the putty is firm) but not yet hard. At this point, the putty is easily cut by a razor blade. When the excess material is cleaved away, the user can “resume” curing by exposing it to sunlight again.
