Dry (internal) strength Resins are multifunctional chemicals which are widely used both to enhance paper / paperboard strength such as bursting, compressing, tensile, and internal bond strength etc. and to improve drainage and retention of fiber, fines and filler.
We have many dry (internal) strength agents that can provide the papermaker a product to meet a wide variety of needs for improved dry strength.
