KK100 Economy is our large can of heavily discounted temporary adhesive spray. It is superior in price and quality to the best spray adhesives in the world. Compare with 505 spray adhesive and you will likely be impressed with its performance and cost considering it is a very big 18 oz. can. Many United Thread customers try economy KK version before purchasing our more costly no-compromise KK-100. Many of these people are very happy with the economy version and they use it for years! Yet, customers who even once try our premium version of classic KK-100 usually become hooked and never use any other temporary adhesive spray in their shop. You may want to save money and first try this great value economy embroidery spray adhesive. Or, try both this and the classic version and compare performance. Either way, you cannot go wrong.
